ROAD nrtnssnn.

Application filed July 21,

' creasing the draft of the machine incident to such accumulation.

Another object is to provide a machine of this character constructed soas to loosen the road material and push it over tofill in 10W places andpast the center of the'machine if it, is not needed to 511 up'low placesand should there be a small amount of road material pushed out at theside of the path passed; over it will be smoothed down and" leveledduring the passage of the ma'chine thereover;

Another object is to provide aroad dresser having grader blades arrangedso that they will fill ruts, ditches and the like from both sides duringthe passage of the machine in one direction and having means to preventdipping of the machine and to produce an even distribution of the roadmaterial.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention residesinthefcombination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be madewithin thescope of what is claimed without de parting from the spiritof theinvention.

In the accompanying drawings: I Figure 1 represents a top plan view of aroad dresser constructed in accordance with this invention. I

Fig. 2 is a side elevation thereof with the rear portions of the'runnersbroken away.

Fig. 3 is a bottom plan view thereof. Fig. 4 is a longitudinal sectiontaken on the line H of Fig. 1 and Fig. 5 is a detail transverse sectiontaken on the line 55 of Fig. 1.

In the embodiment illustrated the machine constituting this inventioncomprises laterally spaced runners 1 and 2 connected by in- 192a serialNo. 652,966. a

termediate spaced cross bars 3 and 4; and a rear cross bar 5 whichcarries a smoothing.

blade hereinafter to be described; A. rod 6 i also connects thereariends ofthe runners at a pointadjacent the bar 5 and is threaded atone end and provided with nut to adapt it to be used for clampinglyconnecting the runners in engagement withthe blade carrying bar 5 whlchis located between the runners withits ends abutting the inner facesthereof. A' scarifier 10 is mounted at the front end of the machinebetween the runs ners land 2 and is composed of twobars or beams 11 and.12 located in recesses 7 formed in the inner faces of the runner-sfThesebars:

11 and'12- are clamping-1y connected by bolts 14 and haveiarrangedbetween them teeth 115 any desired'number of which may be em;

ployed and whichmay be of anysuitable or desired shape for: loosening upthe road material in connection with which the machine,

is to be used.

A metal strap .13 extends acros sjthe-front' end of the machine aroundtheqscarifier 1O and the outer faces of the ends'of the r'unners 1 and2' and are secured by a rod,1-6;

passing through the runners adjacent the scarifien: Clevises'or clips 17are mounted on'the ends of the -rod 16 outside the runners and haveconnected therewith a draftchain 18 designed'to-be attached to anysuitable draft means suchas a tractor or the like.

the inner faces of the runners1and'2 respectively and inclinedrearwardly, and in Grader blades 19 and 20 are mounted on runner blade20 extends at its rear end he 7 'yond the rear end of blade .19 in aplane lapping the plane occupied by' blade 19 and is attach d 2 by abrace 9;.

' .The blades 19 and 20 are carried by beams to cross bar 4 and bracedto runner I scraping action when the machine is drawn over the road. v

The bar 5 is polygonal 1n cross sectlon and its inner face isinclineddownwardly and rearwardly and has securedthereto in.

smoothing blade 25 which is attached to I i any suitable manner thesmoothing blade 25 the lower edge 26 of which projects beyond the barand slightly below the surfaceengaging faces of the runners 1 and 2 .sothat any material pushed out at the side ofthe path passed over by thesecond grader 26 will be smoothed down and leveled by the the runners atright angles and is not intended to out new material butmerely toarticles. i

level the lo0se V 7 this" machine it In the use 0 should be drawn sothat-the rut or low place to be filled in will be located directly underthe implement atabout the center thereof. In

the movement of the machine over the roadway the scarifier 10 willloosen the road materialso that the grader blades 19 and 20 following itwillpush theloosened ma terial into the rut or low place. The frontblade 19 will'push the loose material into the rut some of it perhapsgoing overthe rut and then the following-blade 20 will push the loosematerial from the other side into or over the rut and then the smoothingblade will level or smooth the entire sur-lt'acecovered by the dresser.The runners 1 and 2 which are extended at their rear end beyond thesmoothing blade will opcrate to prevent the smoothing blade from tippingthus insuring an even-distribution of the road material.

" g The overlapping of the plane occupied by thegrader bladesinsures thefilling oi the ruts or other low places from both sides 7 as themachine' passes along in one direction.

The'arrangement of the grader blades at an obliqueangle with a spacebetween them and the runner onthe opposite side of the 7 machine avoidsthe collection of'road material such as would have a tendency to clogthe machine .and increase the draft. .This arrangement of blades alsoprevents any material being forced out tothe sides of the 'machine andthe formation of ridges along the sides of the road which are av greatannoyance to thetravelinig public and detrimental to road maintenance.

A dresser constructed as herein shown and described has no acute anglespresented to the material being dressed such as would operate to catchthe material and carry it with the machine and as abovestated 1t wlllleave no ridges of dirt, rock or the like in it s path and will leave nolumps V therein. V

Various changes in the form, shape, proportion: and other zminor detailsof construetion may be made, without departing from the principleorsacrificing. any'pf the advantages of the claimed invention.

1. A road dressing machine comprising lateral spaced bars'having theirforward ends cut away, a pair of bars having their ends positioned inthe cut away. portion,

said bars having aligning cut away por tions, teeth positioned in thecut away portions, bolts extending through the bars for clamping thebars into close engagement withthe teeth and holding the teeth againstmovement, and leveling members operating at the rear of the bars. V r

2. A road dressing machine comprising lateral spaced bars, teethsupported atone of the ends of the machine, a scraping blade securedtoone of the" side bars and extend- 1 ing at an oblique angle withrespect thereto, a scraping blade secured to the opposite bar andarranged at an oblique angle with re spect thereto, the last mentionedblade extending beyond the inner end of the first j In testimony that Iclaim theiorelgoing as my own, I have hereto affixed my signature.
